Y This invention relates y.to new and useful improvements in lamp shadelholders, the objects being to `provide alanip shade h'older or frameadapted to removably' receive any Yone of a series ofinterchangea'bleadapters or centerpieces whereby such a shade holder can' be used incombination With various styles of lamp` fixtures. Y v `Further objectsof the invention are to provide a series of adapters or attachingmembers having their central portions variouslyrrfornied order "topermit vsaid adapters to beattached `to various lamp Viixtures. Theannular flanges offsaid adapters are i similarly i'ormed:` for enablingany oneV of said adapters to be attached .to a re- ,ceiver portion of ,alampsha'de holder.

It Willbe understood that `shades @r9 formed in various shapesand sizes Vi'or..variouspurposefs, but all of such shade frames `areequipped With collarsA 17 which `are of standard sizkesandl .Y

' dimensionsvv to -fit various fornisofy adapters which arelalso formedoiivsta'ndardl dimensionisti 17j :neY f The form'of adapter shown inFigures t to 6 inclusive, which form is adapted for use with tablelamps, floor lamps, and similar stylesof lamps, comprises a plate 21provided with a central aperture 22 which is designed to receive thethreaded portion b of' a lamp st-andard 10a and is adapted'tobe securedin position on standard 10?L by a nut 10c threaded on portion 19". Theannular portion of plate 21 is cut atl suitable intervals as indicatedat24 to provide prothe' thickness of platev or collar 17 which,

CII

when the adapter is in position', is engaged between said lingers andportions 25 as shown in Figure 6. The peripheral spacing of tongues 28coincides with the arrangement of notches 18 of collar 17 and the widthofV said tongues is slightly less than the-width of said'notches so thatsaid tongues can be passed therethrough in attaching the adapte ed tothe lamp shade frame. i

Plates 21 are of greater diameter than the diameter between the portions19 and when said plate is attached to the shade frame, the edges .ofportions 25 and tongues 28 overlap the edges of portions 19, therebysecurely holding the adapter in position in the frame. The eccentricityof portions 19 facilitates the insertion ofthe adapter in ring 17 andprovides frictional engagement between the edges of said portions 19andthe laterally disposed portions 27 of .tongues 28, Atherebyinterlocking said parts together,

To place the-adapter in position in the frame, said adapter is placed inthe position shown in dotted lines in Figure A2, with the portions 19occupying medial position betweenthe tongues 28 and portions 25. Theadapter isthenfpartially rotated in thel direction indicated by thearrow so as to bring tongues 28 in engagement with portions 19andfrictionally engage the portions 27 of tongues 28 with theeccentrically disposed edges of'portions 19 as shown in Figure 11. InFigures 7 and 8 a modified form of adapter is shown, particularlydesigned for attachment to a lamp socket. The adapter comprises member29 provided with a comparatively Vlarge central opening formed by atubular extension 30 which is attached to said adapter and is threadedfor receiving the threads of a lamp socket 31. rlhe attaching porti/ons25 and 26 are formed in the same manner as the adapter previouslydescribed to receive the portions 1'9 of the lamp shade frame.

In the form shown in Figure 9, an adapter 32 has a tubular extension 34which terminates in an outwardly presented annular` flange 35 adapted tobe engaged by screws 36 of a shade holder 37, now commonly used, whereit is not desired to remove such holder 37. A threaded t-ubularextension 32a may be provided so that said adapter can be attacheddirectly to the lamp socket.

In the form shown in Figure 12, an adaptframe member, a centrallydisposed'ring se-Y cured at its outer edge to said frame and having itsinner edge formed with eccentric ortions, andradially disposed notches,and

an adapter having ya horizontally .disposed annular' edge of greaterdiameter than the opening in said ring for bearing against one sidethereof and formed with lugs offset in a horizontal plane withY respectto ysaid annular portion and adapted to passthrough 'er 38 is providedwith flexible fingersv 39.1' which are designed to engage bulb i() ofY asaid radial notches for engaging the opposite sidev of said ring, saidadapter being provided with a central opening for receiving a` lamplixture.
